Randy & the Rainbows formed in the Queens section of New York City in 1962. The group included two pairs of siblings, brothers Sal Zero and Mike Zero and brothers Frank Safuto and Dominick "Randy" Safuto. Ken Arcipowski rounded out the quintet. The group evolved from the Dialtones, which in 1959 included the Safutos, Rosalie Calindo, and Eddie Scalla, the Safutos' cousin. After recording during the early '60s for Goldisc, the Safutos hooked up with Arcipowski and the Zeros in 1962 to become Randy & the Rainbows.
